中国牵头制定的全球电子通信磁性元件检测领域统一技术规范发布,中国牵头制定的全球电子通信磁性元件检测领域统一技术规范发布_我的网站

A |     　　中新社北京8月25日电 (记者 刘亮)中国国家市场监管总局25日公布，由中国专家牵头制定的国际标准《电子和通信设备用变压器、电感器的测量方法和试验程序》，由国际电工委员会(IEC)与电气电子工程师学会(IEEE)近日联合发布，正式成为全球电子通信磁性元件检测领域统一技术规范。　　国家市场监管总局介绍，该标准的发布标志着中国在该领域正式跻身全球标准引领行列，为5G通信、算力基建、新能源汽车等新一代信息技术与新能源产业高质量发展，筑牢了底层标准根基。　　据介绍，该标准精准适配5G和AI(人工智能)服务器电源、新能源功率变换等前沿产业发展需求，统一规定动态电容、热电偶温升、增量电感、差分电感、能量电感、振幅电感测量等关键测试方法，以及高频工况损耗、交流电阻等十余项试验流程，为全球磁性元件的研发设计、性能检测、质量评定提供了统一、权威的国际技术标尺。　　此前IEC、IEEE两套标准技术要求存在差异，检测结果难以互认，企业出口面临重复检测、多重认证，对国际贸易形成实质性技术壁垒。    On August 15, Ethiopian Airlines flight ET343 was en route from Sudan to Ethiopia when the aircraft’s two pilots fell asleep, according to the Daily Mail.,The Ethiopian Airlines Boeing 737-800 aircraft was cruising at 37,000ft, when alerts were raised on the ground as the plane had approached the airport but did not start to descend.,Air Traffic Control unsuccessfully tried to contact the plane’s crew.,Sometime later, the alarm of the disconnected autopilot awoke the two pilots and they managed to land the plane safely.,The data confirms the incident, which shows that the plane flew over the runway and managed to make another approach when the pilots woke up.,"Deeply concerning incident at Africa's largest airline — Ethiopian Airlines Boeing 737 #ET343 was still at cruising altitude of 37,000ft by the time it reached destination Addis Ababa. Why hadn't it started to descend for landing? Both pilots were asleep,” Aviation analyst Alex Macheras commented the incident on Twitter.,Two and a half hours later, the plane left the airport for its next flight.,A similar incident occurred in April, when, according to reports, two pilots flying from New York to Rome with 250 passengers failed to get in touch with Air Traffic Control for ten minutes and had presumably fallen asleep.。此次发布的标准实现欧亚、北美两大主流技术体系融合互认，建立全球统一测试基准，有助于降低全球企业重复测试与合规成本，打通磁性元件全球供应链技术壁垒。
